Answer to Question #46900 in Mechanics | Relativity for Lucy Kay

Question

A block of mass m is held in place on a ramp of mass M with a slope of angle THETA which in turn is held in place. The ramp is free to move on the surface beneath. There is no friction anywhere. The block and the ramp are then released. Derive an expression for the magnitude of the acceleration of the ramp.(g=gravitational constant is necessary I believe).
